using S32 Design Studio build the example ,error:No such file or directory

hello，when I use the S32 Design Studio for Vision Version 2018.R1 build the examples "apex2_add",I met an error "../A53_src/apu_add_process.h:36:32: fatal error: ADD.hpp: No such file or directory",,an I can not solve it, did anyone can help me?? the error info is below.

2) Did you allow for the indexer to complete its processing after creating the project before attempting to build? Building the project before the indexer has completed could produce unexpected results.

3) Did you attempt to install the VSDK v1.3 on top of the VSDK v1.2 that is provided with 2018.R1? This requires some procedure to implement properly, we are still working to provide a document on this.

4) Are you using the Windows or Linux install of S32DS for Vision 2018.R1? The Linux version requires some additional steps to install correctly.

I got the very same error when I tried update default RTM VSDK v1.2 to v1.3. But when I put back the default version - the missing header error disappear. You can try uninstall your S32DS and install it again.
